Equipments: Coke can, plastic polybag, low density liquid or water, Bunsen burner, thermometer. stop clock. Procedure: You heat the can with the liquid in it to its boiling point and further. This will result in rising of polybag which is attached to the can. This experiment will be performed with various temperatures but others things will remain same. We will measure the height of the polybag that rises with variations in temperatures in a particular time period.  __Independent variable __: temperature or the heat applied __Dependent variable __: height of the polythene bag __Controlled variable: __ mass of the equipments
 * Physics Practical Task (soda can) **

Conclusion: Plastic polybag rises with the help of steam and it will vary with the temperature.
